Katie Winslet’s ‘Titanic’ coat is up for auction

Your coat will go on.

A Coat worn by Kate Winslet Titanic will be auctioned online through September 13 by New Jersey-based collectors auctioneer Goldin.

“It’s definitely in the six figures” Ken Goldin, the auction house’s founder and CEO, told The Post. “It will cost more than $100,000.”

As of Friday evening, five people had already placed bids, the highest being $34,000.

The actress wore this floor-length coat during the downfall scenes of the 1997 blockbuster – as as her character Rose saves Jackplayed by Leonardo DiCaprio, who was tied to a pole on the flooded E deck.

It still has water stains from filming.

Pink wool coat with black embroidery was created by Deborah Lynn Scottwho took home the Oscar for Best Costume Design for her work on the James Cameron film.

In 1998, the film production company 20th Century Fox sold their props from the film, including the coat made by the clothing retailer J. Peterman Companybased on Scott’s design.

The garment was accompanied by a certificate of authenticity from the clothing retailer and 20th Century Fox, confirming that it was worn in the film.

“Then that person kept it for a few years,” Goldin explained of the first buyer, “and sold it in the early 2000s, and the owner who bought it years ago contacted us.”

Then he hired Resolution Photomatchinga company that compares worn items to photos of the person wearing them – to make sure it was exactly what she was wearing.

The elaborate garment is part of Goldin 100, one of the most elite auctions in the auction house’s history, featuring collectible items valued at $100,000 and up.

Goldin predicted that the buyer could range from “any movie memorabilia and pop culture collector” to “a person who may never collect but is a huge fan of the film.”

“It’s a coat, so someone might want to give it to their wife to show off and wear and say, ‘That’s the coat Kate Winslet wore.'”
